Patent DK-57380-A (DK)
Inventor: NIELSEN P T
IPC: H04M/
Filed: 1980-02-11
Abstract: A layout consisting of a central supply unit and an electrical apparatus, which is connected to it by means of two supply lines, can assume either a working status, in which the electrical apparatus is in use, or a resting state, in which the electrical apparatus is not in use. To prevent oxidation of contacts and the like, it is desirable to maintain a resting current, English: "wetting current", in the circuit in the resting state. By controlling the system such that the supply unit in the resting state delivers a current which is less than the working current I subscript 2 and such that the resistance in which the power is dissipated is made smaller in the resting state than in the working state, one achieves a reduction of the power consumption in the resting state. The layout to implement the method comprises a supply unit 1 containing a d.c. generator 2, which can be controlled to function alternately at two levels I subscript 1, I subscript 2 > I subscript 1. The generator 2 can be controlled both directly and in dependency on the voltage across its terminals, so that the state of the generator changes at particular threshold values V subscripts t1, V subscripts t2. The electrical apparatus 8 is provided with a breakable shunt connection 15 with control elements for enabling both direct control and control in dependency on the current strength in the supply lines 6, 7, so that the shunt connection is broken when the current strength exceeds a particular threshold value I subscript t. The change between the resting and the working state can thus be initiated from the control unit 1 simply by changing the current strength between I subscript 1 and I subscript 2, since the coupling of the shunt 11 into and out from the electrical apparatus is controlled by the current strength in the lines 6, 7. Conversely, the shift between the two conditions is initiated from the electrical apparatus 8 by coupling the shunt 11 in and out, since the resulting voltage variations across the terminals of the current generator 2 bring about a shifting between I subscript 1 and I subscript 2. <IMAGE>

Title: Improvements in or relating to apparatus for causing a predetermined variation or predetermined variations in a physical effect
IPC: H05B1/02
Filed: 1919-01-06
Abstract: 139,844. Newcomb, R. W. Jan. 6, 1919. Thermostats.-In an apparatus for producing a predetermined variation or a series of variations in a physical effect, such as heat or light, means are provided for causing the physical effect to vary according to any chosen compound vector representing units of time and units of the physical effect, these means being themselves controlled by the variations occurring in the physical effect. Thus, in the case of a furnace, the temperature in a given time may be caused to undergo a series of predetermined changes, an apparatus for this purpose being shown in Figs. 1 and 2. The supply of gas to the burner 20 is regulated by a valve B controlled by two electro-magnets C, D, and the variations in temperature of the furnace, acting through a thermopile E and the moving coil of a volt-meter V. cause the position of a contact G carried by a pointer F to vary in relation to a rotating drum H. The drum surface consists of two strips of conducting-material J, K separated by an insulating-strip L, the developed shape of which represents the chosen time-temperature vector. The contact G is constrained to follow the line of the insulating-strip L, and the drum is rotated at the desired speed. Should the contact G pass on to either conducting-strip J or K, an electric circuit is completed by way of a pivoted yoke 25 and terminals 28 to one or other of the two electro-magnets C, D, and the valve B is operated to increase or reduce the temperature as required, the alteration in temperature restoring the contact G to its position on the insulating- strip L through the thermopile E and the voltmeter V. The contact G, instead of resting permanently in the drum, is depressed intermittently upon the drum by the pivoted yoke 25, which is raised and lowered alternately by an arm 26 engaging a toothed wheel 27 driven by clock-work mechanism. If the apparatus is required to control the lighting effect of a gas burner or an incandescent electric lamp, the thermopile would be replaced by a selenium cell, and, in the latter case, the valve B by a switch. Reference has been directed by the Comptroller to Specification 138,640.

Title: Improvements in and relating to automatic regulation of the volumes of speech and other audio-frequency currents
IPC: H03G5/20
Filed: 1945-02-01
Abstract: 580,547. Automatic volume control. ARMAN, L. T., and PENMAN, P. R. HUTTON-. Feb. 1, 1945, No. 4/44. [Class 40 (iv)] An automatic volume control system of the kind in which an audio-frequency signal is maintained at a constant level comprises a quick-acting and a slow-acting but more powerful control, the latter acting at different rates according as the volume is rising or falling and being guarded from operation by noise. As shown, a sample of the output signal is rectified at 4 and produces a voltage drop in a resistance 5, 6. The voltage across portion 6 of the resistance acts at once on a valve 10 which controls an attenuator 1. The whole voltage across 5, 6 acts on a valve 9 which controls the attenuator in a similar way, the effect being delayed by the charging of condenser 8 through resistance 13, resistance 12 being effectively short-circuited by a rectifier 11. When the volume is falling, this voltage dies away at a slower rate because 11 is not an effective shunt in these conditions. When the desired signal disappears, the main control circuit is opened at C by a relay R operated over a circuit that discriminates against noise. In these circumstances the charge on condenser 8 is maintained for, say, two or three hours. Alternatively, the relapse of relay R can be made to set the attenuation at some definite value.
